Functional haplotypes of the RET proto-oncogene promoter are associated with Hirschsprung disease (HSCR).
The activation of the RET signaling pathway during embryogenesis is a crucial prerequisite for a directional migration of enteric nervous system progenitor cells. Loss-of-function germline mutations of the RET proto-oncogene are reported in familial and sporadic cases of Hirschsprung disease (HSCR) with a variable frequency. Furthermore, variants of several RET polymorphisms are over- or under-...
متن کاملRET Proto-Oncogene
Hereditary medullary thyroid carcinoma (MTC) is caused by autosomal dominant gain-of-function mutations in the RET proto-oncogene. Associations between specific RET mutations (genotype) and the aggressiveness of MTC and presence or absence of other endocrine neoplasms (phenotype) are well documented. Mutations in six exons (10, 11, 13, 14, 15, and 16) located in either cysteine-rich or tyrosine...
متن کاملThe role of the ret proto-oncogene in human disease.
The ret proto-oncogene encodes a receptor tyrosine kinase with a cadherin-like motif in the extracellular domain. Recently, it turned out that ret is the causative gene for the development of multiple endocrine neoplasia (MEN) type 2A and type 2B and Hirschsprung's disease. MEN 2A and MEN 2B mutations represent activating changes of ret whereas Hirschsprung mutations inactivate ret. In addition...
متن کاملSpecific haplotypes of the RET proto-oncogene are over-represented in patients with sporadic papillary thyroid carcinoma.
BACKGROUND Papillary thyroid carcinoma (PTC), which may be sporadic (95%) or familial (5%), has a prevalence adjusted for age in the general population of 1:100 000. Somatic rearrangements of the RET proto-oncogene are present in up to 66% of sporadic tumours, while they are rarely found in familial cases. PURPOSE In order to determine if some variants of this gene, or a combination of them, ...
متن کاملMutations of the RET proto-oncogene in the multiple endocrine neoplasia type 2 syndromes and Hirschsprung disease.
Distinct point mutations in the RET proto-oncogene are the cause of the inherited multiple endocrine neoplasia type 2 syndromes (MEN 2), and the congenital gut disorder Hirschsprung disease. The site and type of these mutations suggests that they have differing effects on the activity of the receptor tyrosine kinase encoded by RET. The normal function of the RET receptor tyrosine kinase has yet...
